Z 20/0272 it may concern: v i known that I, FRED Brennan citithe Unimd States, and resident oi? Fairport, in the county of lvlonroeand State of New York, have invented certain new and useful Improvements in Lasts-for Makl 'ootwear, of which the following is specification.

T he present invention relates to lasts for making footwear and more particularly to the type in whichthere is employed a fore or toe part and a rear or heel part,co1'inected together in such a manner that'the last may be collapsed and extended at will, .5111 object of this invention is to provide a novel locking means which may be shifted to a position where the last may be collapsed and which upon the expansion of the last,after such collapsing, and-omatically returns to locking position. A- further object of the invention isto provide a novel positive lock in which the locking element may be moved and held out of locking position, so that the "accidental return tosuc'h position is avoided until the last has been collapsed. and again extended. A still furtheiobjeot of'the invention is to' provide a lastwitli a positive locking means which will hold the last against collapsing and'an'impositive locking means which will permit the collapsing of the last under pressure,=the two locking mean being constructed and arranged for substitution, one for the other at will.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

QThese two parts I are, in this instance, pivotally connected together at 3," a \i shape'dnotch 4 being provided above the pivot to permit the collapsing of the last; The hondinginea-iis, in this instance,en1bodies a pair (ii-plates secured in the lier'i': in the iore part1 hv pins 6 and spaced apart at .7 toreceive a portion 8 of a pins 10 in a keri; 11 inthe 'heel part '2; A pro ection 12 extend fromthebonding plate bonding plate 9 which-is in turn Secured by r r 9 forwardly in'the Vshaped notch 4 and this projection is adapted. to move into the" kerf in thei'ore part 1 above the bonding plates 5 when the last fis collapsed; 'Theiorward end 13 'ofthi's projection serves as an abutment for cooperation with theloeking memher or detent 1'51. x 1 The"locking.i'nember or detent 1 1 is, 11; this instance, mounted to swing on the fore part 1. This swinging in .this embodiment is secured providing the locking 'detent let with two slots 15 andfltlj through which headed pins l't'iandlS. extendto secure the locking d'etent 'to the front wall of thefv' shaped notch 4. Suitable means such asa spring 19 securedat'QO to the fore partfand I bearing against the lower end "of the'detent 14 serves normally to move the detent 1.4:

toward loo-hing position, whereas down 'ward pressure'upon the upper portion 21 of the detent will serve. to swing the detent out.

.of locking position and against the action of the spring 19, thus storingenergy in the latter to return the detent automatically to locking position after the detent has been released. The 'detent ll has a locking surface 1 1 on its lateral face which is constructed to just fit under the end of the abutment 13 when the last is in extendedposition and which thus positively locks the last in extended position.

14 also hasa beveled surfaceld on its edge,

Thedetentl alsohas surface 1 on its edge between the surfacesldf? and 14-" which engages the side of the extension or projection 12 on which the. abutment 13 is l ormed when the last is slightly collapsed in order to hold the detent against return movement after being depressed. a a V The last parts become thus slightly rela tively displaced from extended;position;

when the detent isdepressed as shown in if 1g, 2 to; move the-llOSltlVG lOCkingme-aus out of engagement with the abutment, this beinm due to thetension on thelast while shoe. A cooperative relation is thus; automatically established be tween the abutment and the impositive locking surface or me ans 514las the last is t;.-ag in 1 further:collapsed under pressure, and. the detent is {fOlCEECl aside by the pressure be tweentheahutment 1'3 and the'beveled surface 14" uIi-til the abutmentslides past the locking m'emherand enters. the kerf in the ,forepart of the last.
